The greenhouse opening/closing device for adjusting the temperature of the greenhouse includes a bias wire connected to one end of the roller, and a spring having one end fixed to the frame and applying tension to the bias wire in the unwinding direction of the sheet. Characteristic greenhouse opening/closing device. (2) The greenhouse opening/closing device according to claim (1), wherein the tension is applied when the amount of winding up of the roller is equal to or greater than a predetermined amount. (3) A drum connected to one end of the roller and around which the bias wire is wound in a direction opposite to the winding direction of the greenhouse covering sheet, and the spring connects the bias wire and the fixing point. The greenhouse opening/closing device according to claim (1), wherein the greenhouse opening/closing device is inserted between the greenhouses. (4) It has a rotating drum rotatably held at the fixed point and around which the bias wire is wound, and the spring is a mainspring spring that biases the rotating drum in the bias wire winding direction. The greenhouse opening/closing device according to claim (1).
